OSKAR J.W. HANSEN – born 1892 in Langenes/Oksnes

I’m trying to locate Norway-sourced information on my grandfather, who came to America in 1910. There is some history associated with the two names for the same town, located on the island of Svinholmen, in the far northwest. Although I’ve found Norwegian-based info that he is from this town, I’m trying to verify that he was born there, or in the immediate region. I have no info on his parents, although this may exist locally.
